- Removes the `IStyler` service and the `Styler` implementation
- Moves the logic for applying styles and control themes into `StyledElement`
- Removes the style `TryAttach` method from the public API
- Removes style caching for now - this will need to be added back
A few `AutoScrollToSelectedItem` improvements:
- Scroll to current selected item when it's set to true
- Scroll to current selected item when list first displayed
- Scroll to current selected item when attached to visual tree if the selection was changed while it wasn't attached
Fixes#4100
`SelectionModel` needs to subscribe to `CollectionChanged` on the items before `ItemsControl` in order for the selection to be correct when we come to setting the selected state.
Because `SelectionModel.Source` isn't subscribed during initialization in `ItemsChanged`, we also need to make sure we don't subscribe `ItemsControl` to the collection changes during initialization. Instead subscribe in `OnInitialized` (this requires a few tests to be rooted in order to be called).
Fixes#4293
Instead of using `SelectedItems` as the canonical source of selection information, use an internal `Selection` class which keeps track of the selection in terms of item indexes.
Fixes#2004
This is a relic from when we were targeting a PCL profile that didn't have `System.ComponentModel.ISupportInitialize`. Now that we have that, use it instead.
